To all1 whom' it 'rmi/yv concern:

Be'it known that I, EDGAR M. WoRDEN,

aic'itile'n of the United States, residing at Ladysmith, county' ofRusk, and State of Wisconsin, have invented a certaininew and usefulTool for Operating Upon Cotter- Pins, of which the following is aspecification.

My invention relates to an implement to be used in handling Cotter pinsas the same are used in connection With bolts or other operative partsof machinery to key or hold said parts in proper operative position.

A primary object of myinvention is to provide a device having thecharacteristics of ordinary'pliers vvhieih shall nevertheless beespecially adapted tothe work of removing, straightening, and insertingcotter pins from operative. parts of machines, especially automobiles.l

I .-1 further object of my invention is to provide a tool having thecharacteristics above described which shall be simply constructed andhave the parts thereof so arranged as particularly to adapt the tool tothe special purpose indicated and at the same time in nowise interferewith its use as a wrench, pliers, or Wire-cutter. Otller'objectsof myinvention will appear in connection :with the detailed descriptionthereof :rnd are particularly pointed out in the claim.

' In the drawings, which represent one form of my invention-Figures1,2,and are plan views of my tool showing the same in different opera-tivepositions relative to. the Cotter pin. Fig. 4 is a partial plan with thesame portions in section. Fig. 5 is a side view. Fig. 6 is an end View.F ig. 7

.is a view from above of the tool as shown unusually wide spread of saidjaws and the handles,1 as clearly shown in Fig. 1, for a purpose'to belater; described. Each of the circular centr l portions 4 of my tool isprovided with notches 8 WhichI are brought into register when thepincers are partially* opened to be used as wirecutters,.as' clearly.

shown in Fig. 4. Thejaws 5 and 6 are outwardly curved, as shown, and areprovided on the interior .thereof with corrugated surfaces9and.10,respectively, to adapt said jaws to be used as either a pipewrench or nut wrench. The ends of the jaws are provided vvith pinchingsurfaces 11 andv 12, re-

spectively, which are formed so as to meet-l inparallel relation whenthe jaws are closed, as clearlyshown in Fig-3. A

Each of the above features isor'Inayibii` of substantially the characterfound in tools` of this nature inrcommon use.

My improvements are designed to 'adapt this tool, Without interferingin'` any Way with its other uses, to the special function. of handlingcotter pins vused as keys for bolts or other operative parts ofmachines, particularly in connection with automobiles, in which a largenumber of parts arekeyed into position by means'of cotter pins, andwhere the necessity frequently arises of removing said pins for thepurpose of eti`ecting adjustment or repair of such parts. It frequentlyhappens that when the cotter -pin has been removed it will be found. Atobe bent or injured in some .way so .that before it can be reinsertcd tokey on the partirom which A l prongs 14of said cleft being longer thanthe other and adapted to insert under the edge of the eye of a Cotterpin to prythe same up suttlciently to begrasped by a pin 15 to be laterdescribed or inl another position the head of the Cotter pin may bereceived Within the cleft 13 and thereby pried up or lifted. To Withdrawthe Cotter pin fr'om its seat, I provide the pin 15 yvhich isrigidlyextended from the face 12 lof the jaw 6 andiseat's in an opening 16 inthe end of the jaw 5, the pin 1'5afnd the opening 16 extendingsubstantiallyat lright angles to the faces 11 and 12 but" beingpreferably slightly curved, as shovvng. to more` readily permit theinsertion andvvithdrawal of the pin 15 from' the hole 16;"When the eyeof the cotter pin is suii- For eiently exposed or has been pried up eons lio expose. ify by eilher the prong le or the melt' 13, the pin l5Will he inserted through Said eye I and closed into the hole 1G, when,:P5 will be readily imderS'l'ood, the Coller pin .muy he Withdrawn fromills seul, however slrongly wedged therein or bent or fflefornled may hethe condition of said coller pin. lt muy he .noted that the arrangementof die memberl l :1nd 2 so lo `give the Wide spread lo mid members andlhe jaws, when opened, perj jews 5 und 6 with .im extended portion 1Thavin@` therenerose tinnsveree Grooves 18 and l), respectively, saidgrooves .lying in the faeeS of Suid extended portion l? so LhfilV whenthe jews nre closedy lhe grooves will register one above the other inparallel relie tion thus forming round holee or .seals of slighl'l yleSS diameter than that of thecotter pins usually employed.
